Penelitian ini bertujuan untuk mengobservasi pengaruh penambahan inokulasi bakteri asam laktat (BAL) dan aditif terhadap kualitas dan karakterietik silase whole crop sorgum mutan brown midrib (Sorghum bicolor L. Moench) galur Patir 3.7 yang dipanen pada fase soft dough. Penelitian dilaksanakan secara eksperimen menggunakan rancangan acak lengkap pola faktorial dengan 4 ulangan. Faktor A yaitu A1 = tanpa BAL, A2= penambahan BAL. Faktor B terdiri dari B1= tanpa aditif, B2= dedak, B3= jagung. Sumber BAL yang digunakan berasal dari inokulan komersil dari minuman fermentasi merk Yakult dengan dosis 1 ml (v/w) atau 11×109 CFU/ml/berat segar. Aditif terdiri dari dedak padi dan jagung halus digunakan sebanyak 3% (g/g)/berat segar. Parameter yang diamati adalah karakteristik dan kualitas silase meliputi nilai pH, nilai fleigh (NF), kandungan bahan kering (BK), protein kasar (PK), serat kasar (SK), lemak kasar (LK) dan Abu. Data dianalisis berdasarkan analisis keragaman menurut Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa tidak terdapat interaksi (P>0,05) antara penambahan BAL dan aditif terhadap pH, NF, BK, PK, SK, LK dan abu, sedangkan faktor tunggal adititif memberikan pengaruh berbeda nyata (P<0,05) lebih tinggi terhadap kandungan BK silase whole crop sorgum mutan BMR. Dari penelitian ini dapat disimpulkan bahwa secara umum penambahan inokulan BAL dan aditif menghasilkan karakteristik dan kualitas silase yang sama, namun demikian penambahan dedak padi dan jagung halus menghasilkan BK silase yang lebih tinggi dibanding tanpa BAL dan aditif.

Permasalahan utama yang ditemui dalam pengawetan hijauan sumber protein menjadi silase adalah proses pembusukan akibat dari sifat buffer protein yang tinggi dalam hijauan yang mungkin berkaitan dengan rasio karbon:nitrogen (C/N) yang rendah. Penelitian ini bertujuan untuk menguji pengaruh rasio C/N dalam proses ensilage terhadap kualitas silage Chromolaena odorata yang merupakan salah satu hijauan sumber protein. Telah diuji empat perlakuan yaitu C0N = Chromolaeana tanpa penambahan sumber karbon (rasio C/N 14,9); CN20= Chromolaeana + tepung putak (Corypha gebanga) sebagai sumber karbon untuk mencapai rasio C/N 20, atau 25 (CN25) atau 30 (CN30) menggunakan prinsip rancangan acak lengkap 4 × 3. Variabel yang diamati adalah profil organoleptik, proporsi yang rusak, dan kandungan nutrisi silase. Data dianalisis menggunakan analisis varian untuk RAL dan perbedaan perlakuan ditentukan menggunakan Duncan test yang ditetapkan pada nilai Alfa 0,05. Hasil penelitian menunjukkan bahwa meninggkatkan rasio C/N hingga 30, secara nyata meningkatkan profil organoleptik, kandungan bahan organik, protein kasar, serta menurunkan komponen serat kasar dalam silase. Disimpulkan bahwa rasio C/N dalam proses pembuatan silase hijauan sumber protein sangat penting di mana hasil terbaik dicapai dalam penelitian ini adalah rasio C/N 30. Namun, belum dapat direkomendasikan sebagai rasio yang terbaik karena hingga rasio 30, tren pengaruhnya masih berbentuk linear.

Asystasia gangetica is a native plant that has the potential as a superior forage. The potential superiority of A. gangetica is not widely known by farmers in Bali. A study has been carried out with the aim to determine the growth and growth characteristics of A. gangetica as a forage. A completely randomized design with 5 levels of urea fertilizer treatment and 4 replications was carried out at Sesetan Denpasar research station. The results showed that the plant growth indicated by the variable number of branches, number of leaves, and shoot root ratio gave the highest yield on the level of urea fertilizer 50 kg ha-1. Variable characteristics of plant growth such as Leaf Area Ratio, Leaf stem ratio, and plant length, have the same tendency, although they do not show significant differences. Observing the growth and growth characteristics of plants, it can be concluded that the use of urea fertilizer as much as 50 kg ha-1 provides the best growth and application of urea fertilizer exceeding 50 kg ha-1 will adversely affect the growth of A. gangetica. Keywords: A. gangetica, urea, growth, growth characteristics
gangetica是一种具有优良牧草潜力的本地植物。巴厘岛的农民并不广泛了解gangetica的潜在优势。为了确定作为饲料的甘蔗渣的生长和生长特性进行了研究。本试验采用5个水平、4个重复的完全随机设计，在Sesetan Denpasar研究站进行。结果表明，以分枝数、叶片数和茎根比为指标的植株生长在尿素施用50 kg hm -1时产量最高。叶面积比、叶茎比、株长等植物生长的可变特征虽然没有表现出显著差异，但具有相同的趋势。通过对植株生长和生长特性的观察，可以得出氮肥用量为50 kg ha-1时生长最佳，超过50 kg ha-1的氮肥用量将对gangetica的生长产生不利影响。关键词:gangetica，尿素，生长，生长特性

Forage as the main feed for ruminants needs to be considered for availability throughout the year. Factors that influence the availability of forage for feed throughout the year are the influence of the season, the condition of the land, and the presence of soil microorganism. One of the important soil microorganism is nitrogen fixing bacteria (N). This study aimed to determine the population of nitrogen fixing bacteria and soil characteristics in the rhizosphere of legumes and grass at dry land in rainy season. The study was conducted at the Research Station of the Faculty of Animal Husbandry, Udayana University, Pengotan Village, Bangli Regency, followed by a sample analysis at the Animal Production and Microbiology Technology Laboratory, Faculty of Animal Husbandry and the Laboratory of Soil Science, Faculty of Agriculture, Udayana University for 3 months. The design used was a completely randomized design consisting of 5 treatments and 4 replications. The five treatments were non rhizosphere (NR), Gliricidia sepium rhizosphere (RG), Stylosanthes guianensis rhizosphere (RS), Brachiaria decumbens rhizosphere (RB), and Pennisetum purpureum rhizosphere (RP). The variables observed in this study are the population of N-fixing bacteria, N elements, soil acidity (pH), soil temperature, and soil texture. The data obtained from this study were analyzed using annova, if there were significant differences (P<0.05) the analysis was continued by Duncan’s multiple range test. The results showed that the population of N-fixing bacteria, N elements, and soil texture were not significantly different, while the acidity (pH) and soil temperature were significantly different influenced by the rhizosphere of the plant. Based on the results of the study it can be concluded that the population of N fixing bacteria, N elements, and soil texture was not affected by the rhizosphere of the plant, the acidity (pH) of the soil decreases in all rhizosphere of plants, while the soil of temperature increases in Gliricidia sepium and Pennisetum purpureum rhizosphere.

Factors that influence the availability of forage for feed throughout the year are the influence of the season, the condition of the land, and the presence of soil microorganism. One of the important soil microorganism is nitrogen fixing bacteria (N). This study aimed to determine the population of nitrogen fixing bacteria and soil characteristics in the rhizosphere of legumes and grass at dry land in rainy season. The study was conducted at the Research Station of the Faculty of Animal Husbandry, Udayana University, Pengotan Village, Bangli Regency, followed by a sample analysis at the Animal Production and Microbiology Technology Laboratory, Faculty of Animal Husbandry and the Laboratory of Soil Science, Faculty of Agriculture, Udayana University for 3 months. The design used was a completely randomized design consisting of 5 treatments and 4 replications. The five treatments were non rhizosphere (NR), Gliricidia sepium rhizosphere (RG), Stylosanthes guianensis rhizosphere (RS), Brachiaria decumbens rhizosphere (RB), and Pennisetum purpureum rhizosphere (RP).

Lamtoro, a legume tree plant with high protein content that has a wide range of environmental adaptation to dry stress, but relatively limited to acid stress. Mutation of lamtoro through 40 Gy gamma ray irradiation on callus culture produces lamtoro callus candidates adapted with pH 3.4. Aim of the study was to measure the morphological characteristics of adapted lamtoro cv Tarramba pH 3.4 that produced by 40Gy gamma ray irradiation based on differences of cytokinins in tissue culture. The study used complete randomized design with three treatments of different sources of cytokines i.e. kinetin, BAP and TDZ with 10 replications. The results showed that 0.5 ppm TDZ was the best treatment in callus diameter, and produced crumbly callus texture, but showed callus color response that tended to be light green.

The purpose of this experiment was to investigate herbage production and nutritive value of C. ternatea harvested at 60, 75 and 90 days after planting. The legume was planted in eighteen of 3 × 3 m2 plots a t 40 × 20 cm2. Forage was harvested at 60, 75 and 90 days after planting as treatmens. Variables measured included forage production, nutrient content and in vitro dry matter and organic matter digestibility. Herbage production was not significantly different (P>0.05) when harvested at different stages of growth. Leaf : stem ratio, however, declined (P<0.05) with advancing growth stage. Forage quality in terms of crude protein content was comparable (P>0.05) among different harvest time. Meanwhile the energetic value as shown by in vitro organic matter digestibility (IVOMD) was significantly higher (P<0.05) when C. ternatea was harvested 60 days compared to 75 and 90 days after planting. It can be concluded that for calf supplement, C. ternatea is preferably harvested at 60 d after planting. Key words : Clitoria ternatea, IVOMD, energy, calf supplement

This study aims to obtain a study of the productivity of Gliricidia sepium and Indigofera zollingeriana plants which are given various dosage of bioorganic fertilizer. This study used a completely randomized design of factorial patterns of two factors: the first factor was the type of plant (G = Gamal; I = Indigofera) and the second factor was the dosage of bioorganic fertilizer: D0 = without fertilizer; D1 = 5 tons ha-1; D2 = 10 tons ha-1; D3 = 15 tons ha-1; D4 = 20 tons ha-1; D5 = 25 tons ha-1; and D6 = 30 tons ha-1, so there are 14 treatment combinations. Each treatment was repeated three times so that it consisted of 42 experimental units. The variables observed were plant height, leaf number, stem diameter, leaf dry weight, stem dry weight, total herbage dry weight, amount of chlorophyll, ratio of dry weight of leaf / stems, and leaf area per pot. The results showed that the productivity of Indigofera zollingeriana significant higher than Gliricidia sepium. The application of bioorganic fertilizer significantly increased plant height, leaf number, dry weight leaf, stem dry weight, total forage dry weight, amount of chlorophyll, and leaf area per pot, and the highest yield at 30 tons/ha. Based on the results of the study it can be concluded that the productivity of Indigofera zollingeriana is higher than Gliricidia sepium, bioorganic fertilizer increased plant productivity with the highest yield at 30 tons ha-1, and interaction only occurs in the leaf area per pot.
